"Westworld" continued to weave its tapestry of muddled reality with its eighth episode, "Trace Decay." From Bernard's troubling confrontation of reality to new information about the Man in Black, there were plenty of revealing moments.

As usual, several key references or smaller moments may have slipped past you. We're here to round up the most significant details from the episode.

Scroll down for a look at the 11 things you might have missed.

1/

Ford quoted Mary Shelley's "Frankenstein" when talking to Bernard.

HBO

In the episode's opening scene Bernard ( who we learned last week is a host) is distraught over his murder of Theresa. While reassuring him, Ford quoted a line from "Frankenstein."

"One man's life or death were but a small price to pay for the acquirement of the knowledge which I sought, for the the dominion I should acquire," he said.

There are plenty of chilling parallels between Victor Frankenstein, Dr. Ford, and their potentially monstrous creations, making this quote especially apt.

2/

One of Theresa's letters to Bernard revealed that he actually gifted her the lighter we always saw her using.

HBO

Bernard had to destroy all traces of his relationship with Theresa, including small love notes they had written to each other. One of them read:

Bernie, Thanks for the lovely lighter. A flame from my flame. Yours, Theresa

This is a heartbreaking detail, knowing that each time Theresa had reached for her cigarettes and lighter she was thinking of her sweet, loving Bernard.

The woman who tricked Teddy and the Man in Black is the same host who greeted William.

HBO

Angela (played by Talulah Riley) is a host who is part of Wyatt's crew. She trapped Teddy and the Man in Black by pretending to be a damsel in distress.

4/

Angela is the same host from episode two we saw welcome William to the park.

HBO

When the Man in Black saw Angela, he said: "It's you ... I figured they had retired you. I guess Ford never likes to waste a pretty face."

Angela also appeared on the narrative design screen behind Charlotte.

This screen maps out three phases of the new narrative: Lure, Incident, Assault.

On the right you can see Teddy — he's the beginning of the "Lure" for guests who want to fight Wyatt.

Then Angela can be seen under "Incident" — she is one of several hosts who can set a trap for the guests by appearing to be victimized by Wyatt.

The "Assault" comes from the masked Minotaur-esque person.

6/

There was a small clue that told viewers at home what Maeve was going to do next.

HBO

When Felix and Sylvester were about to disobey Maeve and destroy her, she laid down on the maintenance table and gave Sylvester some serious side eye.

Then Felix shut Maeve down, so she froze in place with her eyes on Sylvester. The episode then cut to a different scene for a little bit, but when we came back there was one big change.

7/

Maeve's eyes were now facing upwards — she was awake.

HBO

Maeve's eye movement was the first indication that Felix and Sylvester's plan was not going right. Then a minute later, Maeve sat up quickly and attacked Sylvester. If he had been paying closer attention to her gaze, maybe he wouldn't have been caught off guard.

8/

Speaking of Maeve, we saw Ford use a familiar song to calm her down in the flashback.

HBO

Maeve had a flashback to her critical breakdown as "homestead woman." We learned that the Man in Black had attempted to kill her, and then murdered her child. Afterwards she became so distraught that her programming was failing, and the techs couldn't get her to freeze using regular voice commands.

"Reverie" is closely tied to Arnold.

HBO

"Reverie" was heard back in episode four, when Ford told Bernard about Arnold for the first time in his office. The song seems to have direct ties to Arnold, especially because Ford refers to it as "an old trick from an old friend." Arnold must have coded the hosts to respond to "Reverie" even when their cognition is failing.

Plus, the name of the song echoes Ford's new lines of code that enable memory. Coincidence? We think not.

10/

The flashback scene with Maeve also showed her repeating a line about pain we've heard twice before.

HBO

Maeve was hysterical over the murder of her host daughter, and Ford tried to comfort her. "You need not suffer Maeve," he said. "I'll take it from you."

"No, no, please," Maeve begged. "This pain — it's all I have left of her. Please."

11/

Dolores and Bernard have both said the same thing about their dead loved ones.

HBO

In episode four, Bernard told Dolores that he could make her forget the pain she was feeling when she was grieving the death of her host parents.

"Why would I want that?" Dolores asked. "The pain, their loss — it's all I have left of them."

And Bernard said the same thing in episode three, when his "wife" asked if he wished he could forget their son Charlie. He replied: "This pain, it's all I have left of him."

12/

We saw a familiar face in cold storage — the first Peter Abernathy.

HBO

Charlotte and Lee went down to cold storage in order to select a host they could smuggle out of the park. She happened to choose the host who played Dolores' father in the pilot.

13/

He was retired after a photograph triggered him to subvert his programming.

HBO

The original Peter Abernathy was the first host to use the trigger phrase "these violent delights have violent ends." He also appeared to be crying as he walked into cold storage, after Bernard whispered something unintelligible.

We doubt Charlotte's selection of him as a glorified hard drive will be without consequences.

14/

Two modern songs were played on the piano. The first was "House of the Rising Sun."

HBO

Like all the songs played so far on "Westworld," the 1964 single "House of the Rising Sun" by The Animals was extremely fitting. The lyrics tell a cryptic tale of a brothel in New Orleans, and we know that Maeve's backstory involves her traveling from the UK to New Orleans only to immediately fall into a life of prostitution.

15/

The second song was "Back to Black" by Amy Winehouse.

HBO

"Back to Black" is another thematic choice, with lyrics that match Maeve to a tee:

We only said goodbye with words, I died a hundred times You go back to her, and I go back to black

Maeve's death-count is actually probably in the thousands by now, but you get the point.

16/

Last but not least, the episode title "Trace Decay" is significant.

HBO

Trace decay is a theory of psychology that explains the idea of forgetting and short-term versus long-term memory. The theory suggests that the length of time a memory has to be retained can effect how much it "decays" (or is forgotten).

This relates back to the hosts and their experiences of "reveries" and a warped view of reality. We know that memory doesn't work the same for hosts as it does for humans, and their "trace" of memories is actually written coding that literally cannot decompose.

"Your mind isn't like ours," Felix tells Maeve early on in the episode. "When we remember things, the details are hazy, imperfect. But you recall memories perfectly. You relive them."

Both Bernard and Maeve, along with Dolores, are experiencing uncontrollable, life-like memories that might be pushing them closer to consciousness.
